When trench in t

2、he places where there are underground optical cables, electrical cables and pipes, it is necessary to understand the purpose and location of the underground facilities, contact with the relevant departments, and carry out good protection before construction.2、当挖沟、坑阻碍行人阻碍交通或站内作业时，应在施工地点35m处加设防护，并应当天回

3、填夯实。如需过夜时，需搭人行便桥、通车便道，并设防护栏和警示灯，必要时应派专人监守。在有倒塌危险的房屋、围墙附近开挖时应对其临时加固。When trench affects traffic or station operations, set up protection facilities 3-5 meters from the construction site and backfill and compact the trench the same day. In case of overnight, it is need to take temporary decking across

4、 open trench, set fences and warning lights, and send someone to take care of it when necessary. When trench in the vicinity of houses and fences are at risk of collapsing, it is necessary to reinforce them temporarily.3、严禁在阻碍路基稳定的范围内挖沟、坑，在铁路沿线或穿越铁路挖沟、坑时，摆放的料具和挖出的土石严禁侵入根本建筑限界，并应采取防止塌落的措施。It is prohi

5、bited to trench within the area which would impact stability of roadbed. When trench along the railway or crossing the railway, related materials, tools, excavated earth and rock are not allowed to put into the construction boundary and measures should be taken to prevent collapse.4、电缆、光缆敷设需通过铁路、公路、

6、繁忙车道时开挖时间尽量选择在车辆最低峰进展，并应采取平安防护措施。If optical and electrical cable have to across the rail, road, and busy lane, try to avoid rush hours and should take safety measures.5、挖沟、坑的弃土应距沟、坑边0.4m以外。堆土高度不应高于1.5m。Trench spoil pit should be placed away from the trench by at least 0.4 meter with a height of less

7、 than 1.5m.6、在土质松软地带挖沟、坑时应按斜坡形开挖，坡度的大小应按照土壤的性质、湿度及坑深确定，宜符合下表的规定：When trench in soft soil area, excavate a slope with its angle based on the nature, moisture of the soil and pit depth. The slope should meet the following requirements:沟、坑的坡度表Table of slope of trench and pit土 壤 性 质Type of soil坡 度Slope砂

8、土、淤泥Sandy soil, silt1：0.75砂质黏土Sandy clay1：0.5黏 土 及 黄 土Clay and Loess1：0.3坚 土Pan soil1：0.157、挖水沟、坑及流沙沟、坑时应采纳防护板或沉箱等加固措施。Digging ditches, pits and sandy ditch, pit, reinforcement measures like protection shield or caisson should be taken.8、防护板的安装或撤除应有人监护。严禁将防护板一次全部撤除。强流沙地带不宜撤防护板。Installation or remova

9、l of protection shield should be guarded. It is prohibited to remove all of the protective shields at one time. It is not good to remove protective shield in heavy quicksand areas.9、在架空线路附近开挖沟槽时，应防止架空线路的杆塔倾斜、悬倒。When perform trench excavation in the vicinity of overhead lines, pay attention to preven

10、t slant and hanging down of pole and tower for overhead lines.10、坑底面积小于1.5m2时，坑内不得有两人及以上人员同时作业。沟、坑深大于1m时，不得一人单独作业。If bottom area is less than 1.5m2, only one person can work in it. When the depth of trench and pit depth is more than 1 meter, a person cannot work alone.11、当发生挖坏光、电缆及其它管路事故后，施工负责人应立即通知

11、工程负责人，并同时与设备治理单位联络，确定接续、抢修方法。 If break optical, electrical cable and other pipeline when trench, the person in charge of construction shall immediately notify project responsible person, and simultaneously contact the device management unit to determine the splicing and repair method.12、施工负责人按照抢修原则立

12、即做出决定，如工程部抢修人员在设备治理人员到来之前能够完成抢修工作的，可按照情况提早进展抢修；不能抢修的可派人员配合设备治理单位人员进展抢修。The person in charge of construction shall immediately make a decision in accordance with repair principles. If the repair personnel of the Project Office can complete the repair work prior to the arrival of equipment management

13、personnel, then they can carry out repairs in advance according to the situation; if the repair personnel of the Project Office cannot complete the repair, the Project Office may send personnel to cooperate with the equipment management unit personnel to repair.13、抢修人员要服从负责人指挥。Repair personnel shoul

14、d obey the command of the person in charge.14、在两线间挖沟时，事先在开挖沟两侧铺上塑料布，开挖土放在塑料布上，防止污染石砟。同时如在调车密集地点开挖沟时，要设专人防护员防护，施工人员严禁（坐、卧、躺）等钢轨上，坚决执行，行车不施工，施工不行车规定。When excavate between two lines, put plastic sheeting on both sides of excavation area in advance. Put excavated soil on plastic sheeting to avoid contam

15、ination of ballast layer. Besides, if excavate in area where there is intensive shunting, it is necessary to allocate guard to protect it. Construction workers are prohibited to sit and lie on the rail. Resolutely implement the rule of no construction when train works and no train working when const

16、ruction is performed.15、在超过垂直高度6米护坡路肩上挖沟时，事先把塑料布铺在开挖沟两侧，开挖土放在塑料布上，严禁乱扔开挖土，防止污染石砟。路肩旁要设专职平安员，施工人员严禁坐在路肩侧（坐、卧、躺）等违规行为。When excavate in slope road shoulder of vertical height more than 6 meters, place plastic sheeting on both sides of excavation area in advance. Put excavated soil on plastic sheeting instead of throwing away to avoid contamination of ballast layer. Allocate a full-time security staff along the shoulder in case of any emergency. Construction workers are prohibited to sit and lie on the road shoulder side.交底人Discloser复核Review审核Check接收人：作业队全体人员Disclosee: Operation staff
